In this article we will see how we can trigger on show event in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen).This event is triggered when a window is restored after being minimised, or after being displayed for the first time.
We can create a window with the help of command given below
pyglet.window.Window(width, height, title)
Below is the syntax of the on show event, this method get called when this event is triggered
@window.event def on_show(): print("Window is shown")
Below is the implementation
Python3
# importing pyglet module import pyglet import pyglet.window.key # width of window width = 500 # height of window height = 500 # caption i.e title of the window title = "Geeksforneveropen" # creating a window window = pyglet.window.Window(width, height, title) # text text = "neveropen" # creating a label with font = times roman # font size = 36 # aligning it to the center label = pyglet.text.Label(text, font_name = 'Times New Roman' , font_size = 36 , x = window.width / / 2 , y = window.height / / 2 , anchor_x = 'center' , anchor_y = 'center' ) new_label = pyglet.text.Label(text, font_name = 'Times New Roman' , font_size = 10 , x = 25 , y = 25 ) # on draw event @window .event def on_draw(): # clearing the window window.clear() # drawing the label on the window label.draw() # key press event @window .event def on_key_press(symbol, modifier): # key "C" get press if symbol = = pyglet.window.key.C: print ( "Key C is pressed" ) # on show event @window .event def on_show(): # printing some message print ( "Window is displayed" ) # image for icon img = image = pyglet.resource.image( "logo.png" ) # setting image as icon window.set_icon(img) # start running the application pyglet.app.run() |
Output :
Window is displayed
